If i get 3486.25 points out of 4175 total amount of points, what would be my grade

83.5%

Step-by-step explanation:

B, 83.5%

Step-by-step explanation:

I got you dude, I math this out all the time. You divide how many points you have by how many points total to get the answer. You’ll need 3758 to get a A- (total points x 0.9)

step-by-step explanation:

there is a formula i can give you:

it is r^2*n*sin(360/n) divided by 2 where r represents the "radius" and n is the number of sides.

plug them in:

(10sqrt(3))^2*6*sin(360/6) divided by 2

100*3*6*sin(60) divided by 2

900*sin(60)

900*sqrt(3)/2

450*sqrt(3)

approx is 779.4 cm^2
